Apache Ant - Intellij Idea Community don't recognition for loop command(英语：Intellij Idea Community

Question

我想创建一个 for 循环来迭代文件的行。我做了：

<loadfile property="download.file" srcfile="download_list.txt"/>
<target name="criarArvore">
    <mkdir dir="${download.dir}"/>
    <mkdir dir="${domain.dir}"/>
</target>
<target name="download" depends="criarArvore">
    <for param="line" list="${download.file}" delimiter="${line.separator}">
        <sequential>
            <echo>@{line}</echo>
        </sequential>
    </for>
</target>

但在<for> intellij警告我："无法解析符号'为'"。当我运行脚本时，我收到：

c:xxxbuild.xml:22: Problem: failed to create task or type for
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

Answer 1

<for>任务来自第三方 Ant-Contrib 库。

要使用 Ant-Contrib，请下载 ant-contrib-1.0b3-bin

.zip，从中提取 ant-contrib-1.0b3.jar，然后按照有关如何安装 Ant-Contrib 的说明进行操作。
